The cost of Lipitor, a brand-name drug used to lower cholesterol, can vary depending on the location, pharmacy, and insurance coverage. According to GoodRx [2], the average retail price for a 30-day supply of 20mg Lipitor is $455. However, with a free coupon from GoodRx, the price can be reduced to as low as $9. Additionally, SingleCare [3] reports that the average cost of generic atorvastatin, the generic version of Lipitor, without insurance is $15-$25 for a 30-day supply of 20mg tablets. This price can be further reduced by using a SingleCare discount card, which can bring the price down to as low as $2.84. DrugPatentWatch [1] notes that the patent for Lipitor expired in 2011, which allowed for the production of generic versions of the drug, resulting in lower costs. It is important to note that prices may vary based on location, pharmacy, and insurance coverage.
